Over the years, we’ve seen some of the most insane applications of the ubiquitous LEGO bricks. This must be the most serious build project you can undertake. Jack Streat compiled the assembly instructions for four different guns in LEGO Heavy Weapons. From a Desert Eagle with real blowback action to a pump-action SPAS combat shotgun, there’s a detailed plan for that. Wanna go on full assault mode? Then try the plans for the AKS-74U or go on sniper mode when you build the Lee Enfield jungle carbine. The author includes the parts list for those hard-to-find bricks. Word of warning though, DON’T EVER ATTEMPT to load real ammo in these or you could win a Darwin Award. Seriously, just buy the book and have fun with the build. $25.
